Overview and description of the vinyl player Pro-Ject Xtension 12 Evolution (RS-309D)


The Pro-Ject Xtension 12 player is the flagship of the Classic line and combines the design of the 80's with modern technologies.
The luxurious 20-kilogram body of this model is made of MDF, finished with natural veneer and covered with glossy varnish. As a damping filler, metal granulate is used. Four adjustable magnetic feet of the base provide an effective decoupling from the surface. There is a built-in liquid bubble level in the base, which allows you to adjust the position of the player most accurately relative to the surface on which it is installed. The perfectly balanced support disc weighing 5,7 kg is made of a special aluminum alloy and damped internally with sorbotane, which has vibration-absorbing and anti-resonance properties. To its surface is glued a vinyl mat 4 mm thick. The main inverted bearing with a ceramic ball and a lining has a magnetic suspension system that facilitates smooth rotation, as well as reducing the load on the bearing itself.
The pulley of a powerful electric motor with an ultra-low noise level is connected to the support disc by means of a rubber belt that covers it at the outer edge. The choice between speeds of 33,3 and 45 rpm is electronically due to the integrated quartz speed box DS in the case of the player. The body has a built-in display showing the speed of the currently used speed, and three buttons for switching and fine tuning (in increments of 0.1 rpm). One of these buttons (Speed ​​Change) is combined with the turn of the player. To reproduce the 78 rpm, you will have to manually reset the passek to a larger diameter pulley.
The heavy base for attaching the tonearm has a gasket made of sorbotane and helps to eliminate vibrations and resonances. The model is equipped with a 12-inch tonearm Ortofon RS-309D with dynamic balancing and a vertical clamping force from 0 to 5 grams. The kit includes a dust cover with adjustable hinges, Connect it 5P-C (5 pin DIN-2RCA) interconnect cable with ground wire and a brass clamp. In the role of the power supply is an external network adapter.
With the correct selection of the cartridge Pro-Ject Xtension 12 allows you to get exceptional sound quality, which is characterized by accuracy, musicality, smoothness and ease. This sound is not tiresome and can provide long hours of comfortable listening.
